Which particular bonding exists in ${\text{H}}_2\text{O}$ and $\text{HF}$ but does not exist in ${\text{H}}_2\text{S}$?

Hydrogen bonding occurs specifically when hydrogen is covalently bonded to highly electronegative elements such as Fluorine ($\text{F}$), Oxygen ($\text{O}$), or Nitrogen ($\text{N}$).
Because Oxygen and Fluorine are highly electronegative, ${\text{H}}_2\text{O}$ and $\text{HF}$ exhibit strong intermolecular hydrogen bonding. Sulfur ($\text{S}$) has a much lower electronegativity, so ${\text{H}}_2\text{S}$ lacks hydrogen bonding and exists as a gas at room temperature.
